Active clinical trials for "Heart Diseases"

To investigate the relationship between dietary factors, especially macronutrients, and blood pressure in an international, multicenter observational study. A particular focus is to help elucidate the role of these dietary factors in accounting for the even more adverse blood pressure patterns of less educated population strata, especially in the United States, in both less educated Blacks and whites.

To conduct a randomized demonstration and education trial of churches in East Baltimore testing a self-help, minimal intervention compared with an intensive physical activity intervention.

To study the process of recycling failed smoking cessation attempts and relapses.

To complete end point analysis for the Monitored Atherosclerosis Regression Study (MARS) and to compare coronary versus carotid treatment effect relationships in MARS to coronary versus carotid treatment effect relationships in the Cholesterol Lowering Atherosclerosis Study (CLAS). Both MARS and CLAS were serial arterial imaging trials that explored the reversibility of atherosclerosis with lipid-lowering therapy in native coronary, carotid, and femoral arterial beds, as well as in coronary artery bypass grafts.

To conduct a randomized controlled trial to evaluate the effectiveness of an intervention to reduce dietary fat.

To improve long-term blood pressure BP) control in a predominantly African-American, low SES community of a large city.

To develop a scientifically valid and ethnically approved, lay-led smoking cessation intervention for Southeast Asian men and women, i-e., those from Cambodia, Laos, and Vietnam.

To compare long-term recall of physical activity up to 15 years in the past with physical activity reports and physical fitness levels assessed at the baseline examination.

To conduct a longitudinal study investigating the physical activity patterns, the psychosocial predictors of physical activity, and the effects of physical activity changes on blood pressure and body fatness in a cohort of African-American girls, ages 11-17.

To enhance statistical methods for epidemiological studies by extending the Disturbed Highest Derivative Polynomial (DHDP) to models for binary-logistic and Poisson data and by including random subject effects in the Gaussian model.
